A study from the University of Colorado Boulder and the University of Washington finds that the retreat of the ice sheet covering North America made Antarctic weather more similar from one year to the next.

Heavier snowfall over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.

Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.

A new study in Science, co-authored by the British Antarctic Survey and UW authors, shows that melting of the floating Pine Island ice shelf is tied to global atmospheric patterns associated with El Niño.
